So i just bought my Nintendo DSi yesterday as i had a sudden urge to play DS games again and my old DS (the original model) is all beat up and stuff. Anyways, i decided since i lost most of my games that i should purchase a flashcart to put ROMs on and such. Me, knowing nothing about DS flashcarts and having never used one before, i searched until i found one that looked the most appealing. I ended up purchasing the Supercard DSONEi from this website dealextreme since it was pretty cheap. Anyways,the point of my topic is, what size microsd card should i buy for this supercard to store a lot of ROMs on? Is 4GB enough? I think that's the biggest size they have at Target.
